Patented May 2, 1933 UNITED STATES PATENT OFFICE HAROLD M. WARREN, O EST. PETERSBURG, FLORIDA, ASSIGNOR TO STEEL-BOUND CONTAINER CORPORATION,OF ST. PETERSBURG, FLORIDA, A CORPORATION OF FLORIDA CONTAINERApplication filed June 22,

This invention relates to containers of knockdovvn construction.

An object of the invention is the pr0vision of a container Which isformed of flats, a top and a bottom which may be readily assembled ordisassembled Without the use of nails.

Another object of the invention is the provision of a container in Whichthe side Walls are formed of fibrous materials to Which are connectedflat metal straps or strips having penetrating prongs projecting fromthe metal strips for securing said strips to the vvalls, the end stripson the container providing means for removably securing the heads o fthe bottom and top of the container in position, the free ends of thestraps being removably secured together.

A further Object 0f the invention is the provision of a container havingside Walls, a top and bottom secured together by metal straps havingmeans projecting therefrom for attaching the straps to the side Wallswith anchoring means for the straps and projecting from said straps inclose association with the attaching means, said anchoring meansconsisting of relatively broad curved members which aie adapted to beimpressed into the side Walls.

A still further object of the invention is the provision of a flat whichis formed as a unit in any approved manner and includes a plurality ofspaced strips of fibrous material or a flat sheet of fibrous material towhich are connected thin flat metal strips by means of penetratingprongs having their free en ds clinched over upon one face of thematerial in close association With anchoring means formed by sWaging orcutting the metal bands to provide a relatively b-road resistancesurface.

This invention will be best understood from a consideration of thefollowing detailed description, in view ofthe accompanying drawingsforming a part of the specification; nevertheless it is to be understoodthat the invention is not confined to the disclosure, being susceptibleof such changes and modifications Which shall define no material depar1931.

Figure l0 is a pian view of a flat showing the metal strips disclosed inFigs. l to 3, iiielusive, appiied tc a sheet of veneer.

Referring more particularly to Figs. l to 3, inclusive, it will be seenthat the container comprises a top 20, a bottom 2l and a side Wall 22.

The side Wall in this instance consists of a plurality of strips offibrous material such as Wood, heavy cardboard, either plain or coi--rugated, or some form of composition material suitable for the purpose.These strips of material are secured together by means of flat metalstrips 24, 25 and 26. It will be f noted that the metal strips 25 and 26are substantiallvl identical While the metal strip 24 is varied somewhatin configuration due to the fact that it is located intermediate thelends of the strips of material 23 and must be anchored along itsopposite edges for retaining the metal strip in position.

The metal stripl 25 er 26, as shown more particularly in Figure 3, hasits opposite ends grooved transversely, as shown at 27 and 28 Vbut doesnot penetrate the same.

so that when the ends are fitted together the groove 27 will be receivedwithin the groove 28. rlhe metal strip is cut, as shown at 29 and 30,andthen punched in the opposite direction to the curvature of the groove27 to provide a catch 31. The opposite ends of the strip as shown at 32and 33 are cutand punched outwardly in a directiony which is opposite tothe curvature or groove 28 to provide a seco-nd catch 34 which isadapted to be received within the catch 31 and a Cotter pin 35 isinserted within the co-operating members 31 and 34 for securing the endsof the metal strip 26 o1' 25 together.

The ends of the metal strips 24 are ccn- -structed in a manner which isidentical with the ends of the strips 25 and 26 and are also securedtogether by means of a Cotter pin.

One edge of either the metal strips 25 or 26 is cut as shown at 40 and41 and the material of the metal strips is bent outwardly at rightangles to the plane of the strips to provide penetrating prongs 42 and43. These prongs are forced through the strips of fibrous material 23 orthrough the veneer and the projecting ends of the prongs are clinchedover upon the opposite face of the side wall for securing the metalstrips to said side walls or to the strips of fibrous material 23.

The material of the strips 25 and 26 between a pair of the prongs 42 and43 is swaged inwardly to provide a curved anchoring member 44 and suchanchoring member when the prongs 42 and 43 are forced through the sidewall is impressed into the side wall The anchoring member 44 presents arelatively broad resistance surface and co-operates with the prongs 42and 43 for securely anchoring the metal strips 25 and 26 and likewisethe strip 24 to the side walls. The member 44, however, performs anadditional function which will be presentlv described.

After the top and bottom have been placed in position and are restingupon the upper or lower ends 45 of the side wall 22, as shown in Figure2, portions of the edge 46 of the metal strips which project beyond theopposite edges of the side wall are swaged over as shown at 47 toprovide means for securing the tops and bottoms in position. It will bealso noted that the top and bottom securing means 47 are directlyopposite the curved anchoring members 44 and the anchoring members 44co-operate with the swaged over portions 47 for aiding in retaining thestraps 25 and 26 in position and for rigidly securing the tops andbottom in position since the curved members 44 and the swaged overportions 47 are bent to# Y wards each other. These members will act'yand 7 the flat metal strip 55 is perforated at as a substantialclamping means.

The flats which comprise the side walls arev formed in a machine and themetal strips 24,

25 and 26 are secured directly tothe sideV wall by forcing the prongs 42and 43 through the side walls, clinching them over while at the sametime impressing the curved anchoring members 44 into the material of theside wall.

These flats may be formed into any shape desired to provide a containerand the free ends of the straps are secured together by placing thecatch member 31 over the catch member 34' and then inserting the cotterpins. The bottom 21 is then placed in position with the peripheralportion of the bottom resting upon the lower edges of the side wall 22and the outer projecting edges of the stra-p 26 are then swaged over thebottom so that the bottom is rigidly clamped in position. f-

The containers may then be filled with a comestible after which the top21 is placed in position and the projecting edges 46 of l235 the metalstrips 25 are then swaged over as shown at 47 for securely clamping thetop in position.

The tops 20 may be removed when it is desired to discharge the containerof thevf comestibles by removing the Cotter pin 35, thus'releasing theupper edge of a side wall so that the top 20 may be forced from itsposition. If it be desired to return the shipping case or container toits initialY point of shippage, all of the Cotter pins may be removedand the side walls are then fiattened out and packed together with theirrespective tops and bottoms. It will thus be seen that the re-shippingof the containervr may be done at little expense due to the fact thatthe containers may be formed in neat compact units which will take upvery little space.

In the modied form shown in Figs. 4"

and 5, the strips of fibrous material 50 are connected together by meansof penetrating lprongs 51 punched from a flat metal strip 52 after saidprongs have been forced through the strips or slats 50 and after theends of the prongs have been clinched over the opposite face of thefibrous strips. In the form shown in Figure 5 the punching out of theprongs 51 also provides an anchoring member 53 which has a relatively'Foif instead of forcing the same in flat con!" tact with the metal strip52. It will be noted that the anchoring member 53 is of less length thanthe prongs 51 so that the anchoring member may be impressed into theside wall without penetrating the same.

In the modified forms shown in Figs. 6

56 so that the prongs 57 of staples 58 may Abe inserted through themetal strips 55.,

The prongs 57 of the staples it will be appreico fio

ciated perform the same function as the prongs 51 of the constructionshown in Figs. 1 and 5 and the prongs 42 and 43 of the constructionillustrated in Fig. 3.

At spaced points along the inner edge of the metal strips 55 areprovided anchoring members 59 Which are formed by sWaging the metal ofthe strips inwardly and the staple, as shown at 58a, embraces theanchoring member 59. It Will also be noted that a pair of staples arelocated upon opposite sides of the anchoring member 59 in addition tothe staples 58a.

Referring more particularly to the further modifications shown in Figs.8 and 9 it Will be seen that the elements employed in Figs. 6 and 7 aresubstantially the same except that the arrangement has been varied. Inthis form the staple 60 is employed intermediate a pair of anchoringmembers 61 While a staple 60a straddles the anchoring members. Theprongs 62 of the staples are adapted to be forced through the side Wallmember 63 after they have entered perforations 64 in the metal straps65. The anchoring members 61, however, are adapted to be impressed intothe material but do not cut entirely through the same. rihe tree ends ofthe prongs 62 are clamped over the inner face of the side Wall member63.

Figure 10 discloses a flat which is formed of a sheet of Veneer and apair of metal straps 71 and 72. The straps 71 and 72 are similar in allrespects to the straps 25 and 26 shown in Figures 1 to 3, inclusive. Thesections of veneer 70 are cut into the proper lengths and run through amachine in cooperation with the straps 71 and 72 so that not only theprongs and anchoring members are Jformed upon the straps but the metalstrips are secured to the sheet of veneer 70 by clinching over the freeends of the penetrating prongs which project laterally from the strips.in this case the anchoring members 44 are impressed into the material ofthe veneer 70.

ItWill be noted that I have shown one intermediate metal strip 24 inFigure 1, but it Will be appreciated that any number of metal strips maybe employed Jfor the purpose, depending upon the length or the height ofthe container. Where the height of the container is such that the sameWil have suiiicient strength Without any intermediate metal strips, thesaid strips may be dispensed With.

It Will be noted from Figure 2 that an inner disk 2Oa is applied to theunder face of `the top 20 and the periphery of this inner disk abuts theside Wall of the container.

An inner disk 21a is secured to the inner face of the bottom 21 and hasits periphery in abutting relation With the inner face of the side Wall.
